[Ocfs2-users] ocf2 mount point hangs

[Ishmael Tsoaela]

thanks,

still nothing when using   find / -iname '*suballoc.*'



This code is it:


2398         /* The caller got this descriptor from
2399          * ocfs2_read_group_descriptor().  Any corruption is a code bug. */

2402         trace_ocfs2_block_group_clear_bits(bit_off, num_bits);
2403
2404         BUG_ON(undo_fn && !ocfs2_is_cluster_bitmap(alloc_inode));
2405         status = ocfs2_journal_access_gd(handle, INODE_CACHE(alloc_inode),
2406                                          group_bh,

2410         if (status < 0) {
2411                 mlog_errno(status);
2412                 goto bail;
2413         }
2414
2415         if (undo_fn) {

2417                 undo_bg = (struct ocfs2_group_desc *)

2428                                 (unsigned long *) undo_bg->bg_bitmap);

2430         le16_add_cpu(&bg->bg_free_bits_count, num_bits);
